Specification of Letters Patent.

To all ii 1mm it may concern:

lie it known that l, Enwwun M. llnrmmx, a citizen of the United States,and a resident of South licud, inthc county of fits-Joseph and State of.l'mliana, have invented certain new and useful Ill'lPlOVQlIlQlltS inEngine (hu1gl.lows; and I do hereby declare the following tube a fullclear, and exact description of-the invention, such as will enableothers skilled in the art to which it appertaius to make and use thesame.

This invention relates to im n'ovcments lll plows and more particularlyto such as are drawn by means of a tractor and known in the art asengine gang plows,-one ob ect of the inventionbeing' to so constructanengine. gang plow embodying power lift and manual ad usting means thatthe same may be readily controlled and manipulated by' the operator fromhis seat on the tractor;

A further object is to construct the lifting mechanism in such mannerthat it will pcrate to first raise the forward ends of the plows; thentheir rear ends and finally raise the plow bascsbodil out of the groundin such manner that when fully. raised the plows will be approximatelythe same distance above the ground, from endto end.

A farther object is to construct the mechanism in such manner that whenthe plows are lowered. the forward ends of the plow bases will beloweredin advance of their rear ends and thus cause said bases toquickly enter the ground;

A further object is to provide means which will operate to balance theplow in suehmanner as to enhance the ease with which the plows may beraised, and at the same time reduce to a minimum, wear due to friction.

it-h theseand otherobjects-in view, the invention consists in certainnovel features of construction and combinations of parts as hereinafterset forth and pointed out in the claims.

This link projects forwardly from its connection with thelever 72 and is provided near its forward end [with an elongated slot 74for the reception of a pin 75 at the upper end of an arm or bracket 76rigidly secured to the furrow wheel crank axle '11. v

A--rod or pitman 77 (preferably comprising two members secured together)'is conneoted at one end with the upper arm of the lever 72 and at theother end to the upper arm of the lever of the follower wheel adjustingmechanism.

to be impart-ed, through the 44 As the plow'moves forwardly,

The arm 78 of a notched segment 7 9 is rigidly securedatits lower endtothe furrow-wheel'crank axle 11 and to said segment arm, one end of ahand lever 80 is pivotally. attached,-said hand lever being providedwith a suitable detent to engage the notched segment. A rod 81 (Fig. 1)is connected at itsfforward end .to the hand lever 80 a compara'tivelyshortdistance above the pivotal support of the latter and at its rearend. this rod is pirotally attached to a bracket-arm 82 secured to thecruel: axis 14: and depending below the horizontal portion thereof.

A. spring for counterbalancing the furrow wheel axle, is attached at oneend to a lug 8 1 and the other end of this spring is connected with thesegment I? or its arm '78 by means of a. rod 85 passing through a,

' sleeve 86 pivoted to the segment arm at 87 a and having a nut or head88 at its free end. i A counterbalanoing spring 89 for the land wheelaxle ll is attached at one .end to an arm 90 on said axle and the otherend of this or coupling 6.

Assuming that-it is desired to raise the the operation of the power liftplows by the operator seated on'thetr acwill be imparted,.by therotationfof the fur row wheel, to the cam plateand cam and the etweenits ends. Tothe shorter the cord 63 and. cause motion,

motion latter, coiiperating .with the roller.46,- will,

tend to raise the pivoted frame 38. As the pivoted frame is lockedagainst independent vertical movement by reason ofi-ts connection withthe hand lever which-is locked to the segment Glyit follows that theraising power imparted to the pivoted frame by the operation of the cammust be imparted by said frame to 'the guide bracket $2 on the beam 1,1thus causing the connected beams to be raised.

It will be remembered that the segment arm 78 is-rigidly secured to thefurrow wheel axle 11.; so that whensaid axle is V raised and causedtoturn asabove explamed, said segment arm and, parts carried therebywill move rearwardly. V hen the bower lift mechanism is operated thelever will be locked to the segment 79 at the upper end of the segmentarm and therefore during the rearward, movement of the segment arm andparts-carried thereby, motion will be transmitted, through the rod 81,to the bracket arm 82 on the rear axle LL and cause the axle to beturned, thus raising the landside side of the gang. During the raisingof the for ward ends of the beams, the plow bases will be tiltedupwardly (the follower wheel con stituting a fulcrum for the connectedplows) and hence the points'of the plow bases will be direct-ed in anupward direction and the exit of said bases from the ground will befacilitated. The operations above described will occur during the firstportion of the. raising movement imparted by the cam. As the front endsof the plows are raised, the furrow wheel axle mounted at the forwardends of the beams'will rise also, the spindle portion 12 of said axle 11turning in the hub of the furrow wheel. During the first portion of theupward movement ofthe axle 11 and while the plow bases are being directed out of the ground, thevpin' on the arm 76 secured to said axlewill move freely through the elongated slot 7% in; the link 73. Duringthe continued upward movementof the axle 11, and the plows and afterthepin 7 5 has reached the end of the slot 74 in link 73, motion will beimparted by said link to the lever 72, causing the latter to pull therod or pitman 77. The pulling of the rod or pitman will cause the leverBO-T'jto be turned on its pivotal support to apply down- 1 'wardpressure on the follower wheel for raising the rear ends of theconnected plows. Thus it will be seen that the plow bases will first betilted u wardly and afterward raised bodily from t e ground, so thatwhen theplowsshall have beenfully raised; their bases will each be, thesame distance. from end to end above theground.

When the plows sha pawl 48 lhave been raised as above explained, theroller 56 on the trip -lever 55 will engage the tail of the and releasethe latter from the ratchet Wheel 139 operator to engage the ratchet 47,thus permitting the machine to move forwardly with the plows locked inraised position.

By counterbalancing the axles with springs and by having the crank ofthe land wheel axle set forwardly (as shown in Fig. 1) the raising ofthe plows bymeans of the power lift mechanism will be greatlyfacilitated and slipgping of the furrow wheel will be avoided. y havingthe crank of theland wheel axle set forwardly, the travel of the plowhas a tendency to force the wheel backwardly when the crank of the axleapproaches a vertical position. This not only assists in the raising ofthe plow, but relieves the load from the power lift mechanism at thetime the same is at its full height and when the driving pawl must bereleased from the ratchet wheel. Thus my improved construction enablesthe pawl to be easily forced out of engagement with the ratchet wheel,and in consequence ofthis, the pawl and ratchet wheel are not subjectedto greatwear on account of frictional resistance to their relativemovements.

When it is desired to lower the gang, the

permit the pawl 48 whee -47.- The forward movement of the plow .Jwillnow cause rotation of the cam plate and cam to permit'the descent'iofthe forward ends of the beams. lt'wil l be observed that the forwardends of plow bases will be lowered in advance of the lowering of therear ends and trip lever 55 and thus hence the entrance of the plow 1bases into the ground will be greatly facilitated. This movement islargely due to the operation of the balance spring 35 having sufficientstrength to hold the rear end of the gang up when the front ends of theplow bases are resting on the'ground, and as the plows are drawnforward, the weight of the furrow will draw the plow bases down tocorrect working position. When the plow bases are j-i-n workingposition, the arm 31 on the bear- I Y in'g {sleeve 21 will rest againstthe lower arm engaging the standard v.50,

- bases and the follower wheel 19 will carry the rear end of the gang sothat the landsides of the plow bases will clear the hot.

30 and the adjusting screw 32, 4 of the beam 3, will limit the downwardmovement of the plow o'f the lever toms of the furrows from three-vein?th to one-half inch. I

"It will be observed that when the gang is inhivorking position, thebearing sleeve for the follower wheel axle will incline forwardly. Suchposition of the bearing sleeve and axle'has a'te-ndency to cause thefollower wheel to runmore steadily than if said baa-r ing sleeve andaxle were vertically disposed, and with the assistance of the springlock, the wheel has notendency to run sidewise,--

will pull the cord to operate the at the same time permitting the plow'struc; ture to be backed a short distance so that a plow base can beraised clear of an obstruction. It will be observed that when the plowis raised, the, bearing sleeve 21 and axle 20 will be vertically.disposed, which is the correct position for said sleeve and axle whenthe follower wheel is to caster during the turning of the plowstructure.

With the hand lever mechanism hereinbefore described, the plows may beadjusted for depth of plowing and for leveling the plows, but as thismechanism-constitutes the subject of a separate application for patentfiled concurrently herewith, a detail description of the operation ofthis adjuming mechanism is superfluous herein, except to call attentionto the fact theta-if a' plow base should strike an obstruction whichmight be so located as to preclude the operation of the power liftmechanism, the gang could be raised (after backing the plow from theobstruction) by moving the leverfi?) rearwardly until its detent shallengage the notch 6i at the rear end of the segment 6t.

Various slight changes might be made in the details of construction ofmy invention without departing from the spirit thereof or limiting itsscope and hence I do not wish to restrict myself to the precise detailsherein set forth.

Having fully described my invention what I claim as new and desire tosecure by Letters-Patent, is
